Review Comment:
Why segment should related with the input schema? Actually segment or rowset
has its own schema.

Review Comment:
I find there are some logic that check whether the rowset has tablet schema.
Why not add tablet meta to all rowset during data_dir.load()?
Then we do not need deal with these if else logic.
